WDS Differential pH/ORP Sensor

Walchem’s WDS Series differential pH and ORP sensors are designed for industrial applications to be long-lasting and reliable.

Differential measurement technique uses two electrodes, one for the process measurement and the other for the reference measurement.
    • Replaceable salt bridge for long life
    • Field proven differential design
    • Transmits signal 3,000 feet (915 meters)
    • Walchem preamplifier models are compatible with Walchem controllers
    • Conventional preamplifier models are compatible with GLI and Aquametrix (Lisle Metrix) controllers
    • Resistant to ground loop problem
